Molecular detection of Aichi virus in raw sewage in Italy.
No full textAichi virus (AiV) is suspected to play a role in viral gastroenteritis in humans. In this study, we assessed the presence of AiV in untreated influent sewage samples collected at four wastewater treatment plants in central Italy. AiV was detected in 6 (12.5 %) of the 48 specimens and in all plants. All of the Italian strains showed the highest nucleotide and amino acid sequence identity to genotype B AiV detected recently in Asia, especially in China
Canine kobuviruses in diarrhoeic dogs in Italy.
No full textCanine kobuviruses (CaKVs) are newly recognized picornaviruses recently detected in dogs in the US. By molecular analysis of the whole genome, CaKV that appeared genetically closest to the murine kobuvirus (MuKV) and to the human Aichi virus (AiV), may be classified in the Kobuvirus genus as new genotype (CaKV type 1) within the species Aichivirus A. To date, there are no information on the epidemiology of these novel viruses in other continents. In this study, by screening a collection of 256 dog fecal samples either from diarrhoeic or asymptomatic animals, CaKV was identified in six specimens with an overall prevalence of 2.34% (6/256). All the positive dogs presented diarrhea and were found to be infected by CaKV alone or in mixed infections with canine coronavirus (CCoV) and/or canine parvovirus type 2 (CPV-2). By molecular analysis of the partial 3D gene, all the strains detected displayed a close relatedness with the CaKVs recently identified in the US. This study provides evidence that CaKVs circulate in diarrhoeic dogs in Italy and are not geographically restricted to the North American continent, where they were first signaled
Molecular detection of porcine kobuviruses in Italian swine.
No full textIn this study, fecal specimens (n=260) collected from Italian healthy pigs aged between 6 and 10 months were screened by RT-PCR using generic kobuvirus primers. Porcine kobuviruses (PKVs) were detected in 3.85% of the samples tested. Based on the analysis of the partial 3D gene, the Italian sequences identified here were more closely related to PKVs previously identified in Japan, Thailand, Korea, China and Brazil than to the European PKVs recently detected in Hungary and in the Netherlands
Molecular detection of bovine kobuviruses in Italy.
No full textFaecal samples obtained from either asymptomatic or diarrhoeic calves in Italy were screened for bovine kobuviruses (BKVs) using specific primers. BKV RNA was detected in 4.9 % of the samples, with higher positivity rates in diarrhoeic calves (5.3 %) than in asymptomatic animals (4.8 %), although the difference was not statistically significant. Upon sequence analysis, all of the Italian viruses formed a tight group along with BKV-like sequences previously detected in Thailand and Japan.[...

Genetic heterogeneity of bovine noroviruses in Italy
No full textBy screening 104 faecal samples from asymptomatic calves in Italy, bovine norovirus RNA was detected with a prevalence rate of 10.5 % (11/104). A continuous sequence spanning the RdRp region and the 5′ end of the capsid gene was generated for 7 of the 11 strains. Upon phylogenetic analysis, five strains were grouped with GIII.2 Newbury2-like viruses, and one strain was grouped with GIII.1 Jena-like noroviruses. Interestingly, one strain (80TE/IT) was genetically related to the GIII.1/Jena/80/De in the RdRp but resembled the GIII.2/Newbury2/76/UK in the capsid gene, suggesting a recombination event occurring in the ORF1/ORF2 junction region. © 2014, Springer-Verlag Wien
Integrated Approaches to Combatting Childhood Obesity
No full textBackground: The global prevalence of childhood obesity has grown sharply in recent decades. Obesity is considered a public health problem which directly affects the health status of children in numerous ways. To combat this trend, integrated approaches are necessary to prevent childhood obesity. Strategies require a comprehensive perspective at individual and parental level alongside the adoption of measures to engage the community and environment. Summary: Prevention is addressed as crucial in limiting the pediatric obesity epidemic in the long term. Breastfeeding and appropriate complementary feeding are recognized as early dietary factors that affect the future risk of obesity development during the first 2 years of life. During childhood and adolescence, dietary patterns, eating habits, portion size, eating frequencies, and family meals are important dietary factors to target for preventive strategies, as well as parenting style which is influenced by parents' education. Physical activity promotion and the reduction of sedentary behavior are also recommended. The adherence of children and families to obesity prevention programs is highly dependent on socioeconomic factors. Moreover, setting food quality standards and public policies to promote healthy lifestyle habits is strongly advocated. The implementation of cost-effective preventive strategies is of high priority and requires an integrated approach by healthcare services. All stakeholders involved should take an active role in supporting and empowering children and families in order to cope with this multifactorial and complex disease
Fat-Soluble Vitamins Deficiency in Pediatric Cholestasis: A Scoping Review
No full textBackground: This review aims to identify the current indications and gaps in the management of fat-soluble vitamins in pediatric patients with cholestasis. Methods: A comprehensive review of the literature using PubMed, Scopus, Web of Science and Embase was performed. Two authors independently identified the most relevant studies published over the past 20 years up to February 2022, including original papers, narrative reviews, observational studies, clinical trials, systematic reviews and meta-analyses. The literature was screened, and preclinical studies about pathogenetic mechanisms were also included. Keywords searched for each fat-soluble vitamin (A, D, E and K), alone or in combination, were "cholestasis", "chronic liver disease", "biliary atresia", "malnutrition" and "nutritional needs". Studies published prior to the selected time range were searched manually and, when considered relevant, included within the list of references. Results: Eight hundred twenty-six articles were initially screened. From these, 48 studies were selected. A comparison of the recommended methods of supplementation for fat-soluble vitamins was then carried out. The causes of malabsorption were explained and current methods for defining deficiency and monitoring complications were summarized. Conclusions: According to the literature, children with cholestasis are at a higher risk of fat-soluble vitamin deficiency. Although there are general recommendations, the treatment for vitamin deficiency is not uniformly validated
Molecular detection of kobuviruses in European roe deer (Capreolus capreolus) in Italy
No full textKobuvirus RNA was found in 6.6 % (13/198) of stool specimens from roe deer (Capreolus capreolus) captured during the regular hunting season. Upon sequence analysis of a fragment of the 3D gene, nine strains displayed the highest nucleotide sequence identity (91.2-97.4 %) to bovine kobuviruses previously detected in either diarrhoeic or asymptomatic calves. Interestingly, four strains were genetically related to the newly discovered caprine kobuviruses (84.2-87.6 % nucleotide identity) identified in black goats in Korea
Health effects of yogurt consumption during paediatric age : a narrative review
No full textYogurt is a fermented milk product characterised by a peculiar nutritional composition with live and viable cultures of bacteria. Few studies have analysed the benefits of yogurt consumption on health outcomes during paediatric age. Recent epidemiological studies evaluating the nutritional impact of yogurt have demonstrated its significant contribution to nutrients intakes among children. Thus, consuming yogurt is a strategy to achieve recommended nutrient intake and healthier dietary choices, with potential impact on obesity and cardiometabolic outcome in children. Yogurt's effects on paediatric infectious diseases, gastrointestinal diseases and atopic-related disorders are ascribed to the specific probiotic strain administered. Interestingly, the benefits of yogurt consumption are most likely due to effects mediated through the gut microbiota and the enhancement of innate and adaptive immune responses. Therefore, supplementing standard yogurt cultures with probiotic strains could be useful to promote health at different paediatric ages, although more evidence is needed regarding the strain-related effects and their interplay within the paediatric immune system
